Should I go to the hospital?

I'm 39 weeks today, me and my boyfriend had sex this morning to try to kickstart this labor and ever since then I've been having cramps in the lower part of my belly and lower back pain and now I'm having a lot of pressure and pain in my vagina (feels like he's trying to push his way out). My last appointment on Wednesday I was dilated to a 3 and 60% effaced.
